pys60 (the full name is python for series 60) 1.1.3
provide both camera and graphics display.
So, it is trivial to take photo and preview.

from appuifw import *
import camera

canvas=Canvas()
app.body=canvas

running=1
def quit():
    global running
    running=0
app.exit_key_handler=quit

while running:
    image = camera.take_photo(size= (160,120))
    canvas.blit(image, target=(8, 12, 168, 132))  # center it

Here I use the small size (160x120) for preview.
When the real photo is taken I can use the full (defualt)
size of (640x480) on my 6600 phone.

Preview what you type in an input or a textarea out of them (in a html tag, like a p, hx...)

javascript code:

function preview(id1, id2){
	  		var NewText = document.getElementById(id1).value;
	  		splitText = NewText.split(/\n/).join("<br />");
	  		var DivElement = document.getElementById(id2);
	  		DivElement.innerHTML = splitText;
}

html code:

<form action="#">
<label>Name:</label>
<input type="text" id="nombre" onkeyup="preview('name', 'preview-name');" />

<label>Phone:</label>
<input type="text" id="phone" onkeyup="preview('phone', 'preview-phone');" />
</form>

<h2>Preview</h2>
<dl>
	<dt>Name:</dt>
	<dd id="preview-name"></dd>
	<dt>Phone:</dt>
	<dd id="preview-phone"></dd>
